    A Windows bitmap with the given mode and size.  The mode can be one of "1",
    "L", "P", or "RGB".

    If the display requires a palette, this constructor creates a suitable
    palette and associates it with the image. For an "L" image, 128 graylevels
    are allocated. For an "RGB" image, a 6x6x6 colour cube is used, together
    with 20 graylevels.

    To make sure that palettes work properly under Windows, you must call the
    ``palette`` method upon certain events from Windows.

    :param image: Either a PIL image, or a mode string. If a mode string is
                  used, a size must also be given.  The mode can be one of "1",
                  "L", "P", or "RGB".
    :param size: If the first argument is a mode string, this
                 defines the size of the image.

        The destination and source areas are given as 4-tuple rectangles. If

        Installs the palette associated with the image in the given device
        context.

        This method should be called upon **QUERYNEWPALETTE** and
        **PALETTECHANGED** events from Windows. If this method returns a
        non-zero value, one or more display palette entries were changed, and
        the image should be redrawn.

        :param handle: Device context (HDC), cast to a Python integer, or an
                       HDC or HWND instance.
        :return: A true value if one or more entries were changed (this
